| Remarks | Two minutes after the sky lit up there was a huge boom that travelled from east to west. Somewhat like thunder, drawn out over about 3 seconds and building to the final boom that shook the house. A post from people south of us near Camrose reported hearing a hissing that made them look up to see the fireball, then the sonic boom two minutes later. Friends near Lindbrook and Ardrossan reported house shaking as well. |
